The ultrasonic town is a patented technology with a shaped energy cover， which increases the effective humidification amount by -% per hour. What are the reasonable aspects of the design of the quick freezing warehouse?
HolkinExpensive， high machining precision of body parts; High noise during compressor operation; Screw compressor can only be used in medium and low pressure range， not in high-pressure occasions; Due to large fuel injection and complex oil treatment system， there are many auxiliary equipment of the unit.
The refrigerant charge is insufficient. At this time， just add enough refrigerant.
OldenburgGenerally， in the actual operation of the refrigeration system， because the temperature conditions are constantly changing， only by relying on the careful operation of the cold storage management personnel and accurately adjusting the operation of the refrigeration equipment of the cold storage， can the refrigeration system always be in the ideal working state and achieve the effect of energy saving.
With the increasing use of cold storage， cold storage board， as an important structure of cold storage，HolkinCold storage maintenance and installation， is also increasing. Because cold storage is different from other ordinary cold storage， it is important to the installation environment and temperature. Therefore， some small problems may be ignored during installation. According to the following understanding.
There are many kinds of cold storage. According to the material， it can be divided into color steel plate， stainless steel plate and salted steel. Among them， color steel plate has strong anti rust ability but stainless steel plate has strong anti rust ability， while salted steel has both beautiful appearance and anti rust ability. According to the layout， it is divided into flat plate and wave plate. The former is flat after the surface material is formed， and the latter is rugged after the surface material is formed. According to the thickness and color of surface materials， the thickness of stainless steel is .mm and mm， without color requirements; The thickness of salted steel plate is .mm without color requirements; The thickness of PE paint baking board is .mm， .mm ivory white， titanium white and white gray. The most important thing for the cold storage is the applicable temperature of the cold storage. It is divided according to the insulation thickness of the storage plate. The thickness of the sky floor of the mm storage plate is mm， and the thickness of the vertical plate is mm and mm， which is suitable for the insulation conditions of - ℃ ~ - ℃; mm storage plate: the thickness of the ceiling plate is mm and the thickness of the vertical plate is mm， which is suitable for the thermal insulation conditions of ℃ ~ - ℃. The thickness of the ceiling plate and the vertical plate of mm storage plate is mm， which is suitable for the thermal insulation conditions above ℃. In fact， there are many other classification methods of cold storage. Determined by the current processing technology， it can be divided into standard plate and non-standard plate according to the width and size range of warehouse plate， including standard plate vertical plate width wa = mm， heaven and earth plate width WB = mm， vertical angle plate W = mm， W = mm，HolkinHow much is the installation of small cold storage， W = mm and W = . The dimensions of non-standard plates are different from those of Wa， WB and W.
Secondly since the cooling of the compressor is not continuous， the multi work operation at night can be selected if possible. When working at night the external temperature is low， the cooling water temperature is reduced， and the condensation pressure and condensation temperature are reduced. The cooling capacity of the sampling system， coupled with the equal role of the cold storage board， reduces the power operation of the compressor and achieves the purpose of energy saving.
After startup， first listen to whether the sound of the compressor is normal，HolkinInstallation price of cold storage， and see whether the condenser and cooling fan operate normally.
The insulation board of the cold storage adopts polyurethane double-sided color steel plate. The main effect of this cold storage insulation board is good sealing performance， insulation effect and moisture-proof effect， so as to ensure the refrigeration effect of the cold storage. The electric cold storage door is adopted for the cold storage door， so as to avoid the loss of refrigeration capacity of the cold storage.
Inspection standardThe temperature and humidity in the warehouse shall be kept uniform without movement; Try to finish the food in the warehouse at one time.
Fault phenomenon: high current or tripping during unit startup， and problems of user air switch; Input voltage is too low; The star angle conversion interval is too short (it should be ~ seconds); Hydraulic cylinder failure (no reset); Intake valve failure (too large opening or stuck); Loose wiring; Host failure; Main motor fault; TR time relay is broken (relay unit).
The assembled cold storage body often adopts double-sided color steel plate of polyurethane thermal insulation material， which has excellent thermal insulation performance， storage and circulation effect and reduces operation energy consumption. Of course， more important is the choice of refrigeration system. For example， at present the refrigeration system of fluorine refrigerant is still the mainstream， but when selecting the type and power of cooling equipment， it is necessary to calculate the data for the installation of cold storage， professional cold storage installation， cold storage installation， cold storage construction， fruit preservation cold storage， medical cold storage， safety， environmental protection and economy! The products are exported to foreign countries and are deeply trusted. Defrosting and drainage can be discharged immediately. Electric heat tracing and insulation can be selected for the defrosting and drainage pipeline of the warehouse location.
Free consultationThe refrigeration equipment in the fresh-keeping environment of the quick-frozen warehouse mostly adopts the single-stage compression refrigeration system， with freon as the refrigerant. The evaporation mode in the warehouse is the cooling fan， the mode of multiple heads in parallel can be considered.
The air washing and ventilation of the cold storage is in the long-term sealed LIUCai storage， and the carbon oxide is released due to the respiration of vegetables. If the accumulation is too high， it will have an adverse effect on the storage of vegetables. Therefore， ventilation device or air washing device is designed in the general warehouse.
Connect the refrigeration system. Wires and copper pipes shall be used to connect the refrigeration unit， electric control system and other components of the cold storage. The connecting pipes shall be closely connected， and corresponding thermal insulation and protection measures shall be taken.
HolkinWhether there is dirt on the condenser and poor heat dissipation will lead to too high condensation pressure of the refrigerator. In order to protect the compressor， the machine stops running under the action of the pressure controller. When the heat dissipation is good， press the black reset button on the pressure controller， and the machine can automatically resume operation.
Able to withstand the harsh local climate and its changes. Neither high temperature nor severe cold climate will cause irreversible damage or deformation to the external insulation system. The drastic change of the surface temperature of the external wall， such as the sudden shower after a long time of exposure， or shading during exposure， will not cause damage to the surface of the cold storage.
Vent valve or water seal well shall be set at the outlet of flushing (thawing) drainage pipeline. Cold proof measures shall be taken for exhaust valves and water sealed wells in severe cold areas.
